Description

Technical Field

[0001] The present invention relates to a seat attachment structure for connecting a vehicle seat to a longitudinal adjustment mechanism and / or a vehicle floor structure, wherein the seat attachment structure has a first attachment side that can be connected to the vehicle seat and a second attachment side that can be connected to the longitudinal adjustment mechanism and / or the vehicle floor structure, and the present invention also relates to a vehicle seat. Background Art

[0002] Seat attachment structures for seats (such as fastening arrangements and / or seat carriers) are known in the prior art. For example, a seat can be detachably fastened to a guide rail arrangement and / or a vehicle floor structure by means of hooks or screws, or non-detachably fastened to a guide rail arrangement and / or a vehicle floor structure by means of a welded connection. Summary of the Invention

[0003] Objectives

[0004] The present invention is based on the objective of improving a seat attachment structure of the above-mentioned type, in particular by incorporating a tolerance compensation function or a tolerance adjustment function that can be used independently of the tolerances from the structure, and providing a corresponding vehicle seat.

[0005] Solutions

[0006] The above objective is achieved according to the present invention by a seat attachment structure having the features described in claim 1. The second objective is achieved according to the present invention by a vehicle seat having the features described in claim 10.

[0007] Improvements and embodiments of the present invention are the subject matter of the dependent claims.

[0008] A seat attachment structure for connecting a vehicle seat to a longitudinal adjustment mechanism and / or a vehicle floor structure according to the present invention has at least one first attachment side that can be connected to the vehicle seat and a second attachment side that can be connected to the longitudinal adjustment mechanism and / or the vehicle floor structure, wherein the second attachment side includes at least one attachment opening extending along a transverse direction, and at least a tolerance compensation device is arranged in the attachment opening for compensating, in particular adjusting, tolerances in at least one spatial direction (in particular the transverse direction, the vertical direction, and / or the longitudinal direction). The tolerance compensation device can be particularly arranged to adjust the transverse tolerance between the vehicle seat and the longitudinal adjustment mechanism or between the vehicle seat and the vehicle floor structure.

[0009] For example, the tolerance compensation device may include at least one bearing bush and / or sleeve, and two compensation elements that are positioned opposite to each other and arranged in the bearing bush or sleeve. In the initial state, the two compensation elements are each flush with the corresponding end face of the bearing bush, and can be moved from the initial state to the compensation state by means of at least one connecting element (such as a screw element). For example, the bearing bush can be designed as a separate component. For example, the attachment carrier of the seat attachment structure may include two carrier sides that are spaced apart from each other in the lateral direction, and the carrier sides can be connected via a sleeve, and the bearing bush is received and held in the sleeve.

[0010] Alternatively, the bearing bush can be omitted, and only the sleeve for receiving and storing the compensation elements is provided. The bearing bush can also be designed as a sleeve, or the sleeve can be designed as a bearing bush to connect the two carrier sides to each other.

[0011] For example, in the initial state, the compensation elements can each be arranged flush with the corresponding end face of the bearing bush and / or sleeve, and can be moved from the initial state to the compensation state by means of at least one connecting element.

[0012] By including at least one attachment opening extending in the lateral direction in the second attachment side, and arranging the tolerance compensation device in the attachment opening, it is possible to bridge, in a simple and easy manner, especially compensate for or adjust the tolerance-related gaps (such as assembly gaps) between the seat attachment structure and the longitudinal adjustment mechanism and / or the vehicle floor structure.

[0013] Advantageous embodiments that can be used alone or in combination with each other are the subject of the dependent claims.

[0014] The tolerance compensation device can be a separate adapter or a separate adapter module. The tolerance compensation device can be easily integrated into the existing seat attachment structure.

[0015] For example, each compensation element can be configured as a sliding element. In this case, the attachment opening can have dimensions larger than the dimensions of the compensation element, especially larger than the dimensions of the sliding element. Each compensation element can also be pre-installed or loosely pre-installed in the bearing bush and / or sleeve. In particular, each compensation element can be arranged in the bearing bush and / or sleeve in a self-centering manner. In other words, the seat attachment structure with the tolerance compensation device can be designed as a self-centering connector, which has tolerance adjustment in at least one spatial direction (especially perpendicular to the connection direction, in the connection direction and / or the radial direction of the attachment opening). In this way, the remaining tolerances during the assembly process can be easily adjusted, and / or the vehicle seat can be aligned with respect to the longitudinal adjustment mechanism and / or the vehicle floor structure.

[0016] For example, in order to connect to a vehicle seat, the seat attachment structure may include at least one attachment carrier. For example, each attachment carrier may have, for example, two seat mounting attachment surfaces arranged parallel to each other. An attachment carrier may be provided for each rail arrangement structure (also referred to as a pair of rails having an upper rail and a lower rail).

[0017] In order to connect to a longitudinal adjustment mechanism and / or a vehicle floor structure, the seat attachment structure may include at least one fastening structure. For example, the fastening structure may have two rail mounting attachment surfaces arranged parallel to each other. A fastening structure may be provided for each rail arrangement structure.

[0018] For example, a vehicle seat may be a single seat and / or a bench. For seating applications, such as in the second or third row of a vehicle, for example, the vehicle structure is typically equipped with rails, for example, each seat and / or bench is equipped with two rails (in particular, two rail arrangement structures or two pairs of rails, each pair of rails having an upper rail and a lower rail) to allow seat adjustment in the longitudinal direction, such as for comfort adjustment and / or easy access. In order to increase the load-bearing capacity required for the rails, it may be necessary to distribute the load over more than two rails. For example, many vehicle structures are provided with more than two rails. For example, four rails may be provided for a full-length seat, which may cause the entire system to be overloaded, for example, due to alignment errors, tolerance errors, and / or play errors between the seat and the longitudinal adjustment mechanism and / or the vehicle body, where such errors may potentially cause unnecessary jamming and / or interference noise during the adjustment process.

[0019] A tolerance compensation device is provided to reduce, in particular eliminate, the errors. Implementing tolerance compensation or tolerance adjustment between the seat attachment structure and the rails of the longitudinal adjustment mechanism and / or the fastening structure of the vehicle floor structure can eliminate the overload.

[0020] For example, an intermediate rail (also referred to as a rail arrangement structure) or a track can be easily connected to the seat attachment structure. The second attachment side portion may be configured as a fastening arm and / or a seat carrier. The second attachment side portion may be designed to connect a vehicle seat to an intermediate rail / rail arrangement structure in a longitudinal adjustment mechanism having more than two rails / rail arrangement structures. The second attachment side portion may serve as an interface to the rails.

[0021] Furthermore, the present invention relates to a vehicle seat having the aforementioned seat attachment structure.

[0022] In summary and in other words, the present invention provides a seat attachment structure having a tolerance compensation function or a tolerance adjustment function, wherein the tolerance compensation device includes at least two compensation elements designed as sliding elements (in particular adapters), and the sliding elements are installed, in particular pre-installed, in bearing bushes within the seat attachment structure. The compensation elements can move relative to each other at least in the lateral direction (Y direction), and alternatively or additionally can move relative to each other in the longitudinal direction, the vertical direction, and / or the radial direction, and can independently find their positions, in particular compensation positions, based on the tolerances of the seat attachment structure relative to the pre-installed guide rails and / or floor fastening elements in the vehicle.

[0031] In all the figures, corresponding parts are marked with the same reference signs. Detailed Description of the Invention

[0032] Figure 1FIG. schematically shows a vehicle seat 100 in the prior art, which will be described below using three spatial directions extending perpendicular to each other. When the vehicle seat 100 is installed in a vehicle, the longitudinal direction x extends substantially horizontally and is preferably parallel to the longitudinal axis of the vehicle, which corresponds to the habitual driving direction of the vehicle. The transverse direction y perpendicular to the longitudinal direction x is also arranged horizontally in the vehicle and extends parallel to the vehicle's transverse axis. The vertical direction z extends perpendicular to the longitudinal direction x and perpendicular to the transverse direction y. When the vehicle seat is installed in the vehicle, the vertical direction z preferably extends parallel to the vehicle's vertical axis.

[0033] The position and direction references used, such as front, rear, top, and bottom, are, for example, based on the perspective of a passenger sitting in the vehicle seat 100 in a normal sitting position, where the vehicle seat 100 is installed in the vehicle in an operating position suitable for passenger transportation, with the backrest 104 upright and conventionally oriented in the driving direction. However, the vehicle seat 100 can also be installed or moved in a different orientation, for example, transverse to the driving direction. Unless otherwise specified, the vehicle seat 100 is designed to be mirror-symmetrical with respect to a plane extending perpendicular to the transverse direction y.

[0034] The backrest 104 can be pivotally arranged on the seat part 102 of the vehicle seat 100. For this purpose, the vehicle seat 100 can optionally include a fitting 106, in particular an adjustment fitting, a pivot fitting, a locking fitting, or a tilting fitting.

[0035] The position and direction references used, such as radial, axial, and circumferential directions, are, for example, related to the rotation axis 108 of the fitting 106. Radial means perpendicular to the rotation axis 108. Axial means the direction of the rotation axis 108 or parallel to the rotation axis 108.

[0036] The vehicle seat 100 can optionally include a longitudinal adjustment mechanism 110. For example, the longitudinal adjustment mechanism 110 includes a guide rail arrangement 112 with a first guide rail element 114 and a second guide rail element 116. The first guide rail element 114 can be adjusted relative to the second guide rail element 116 in the longitudinal direction x. The second guide rail element 116 is fastened to a structural component of the vehicle, such as the vehicle floor.

[0037] For the sake of clarity, in the following description, the first guide rail element 114 is referred to as the upper guide rail 114. This upper guide rail 114 (also referred to as a sliding guide rail or a slide) is associated with the vehicle seat 100 and is arranged to support the vehicle seat 100. The second guide rail element 116 is referred to as the lower guide rail 116 below. The lower guide rail 116 is, for example, fixedly connected to the vehicle floor.

[0038] The vehicle seat 100 may in particular include two rail arrangements 112 arranged parallel to each other as a longitudinal adjustment mechanism 110. The two rail arrangements 112, each designed as a pair of rails, are arranged, for example, spaced apart and parallel to each other. Unless otherwise specified below, the two pairs of rails may be substantially identical in structure and correspond to each other structurally and functionally.

[0039] In order to connect the vehicle seat 100 to the longitudinal adjustment mechanism 110 and / or the vehicle floor structure 109, the vehicle seat 100 may be provided with a seat attachment structure 200, such as a seat carrier structure. The seat attachment structure 200 is arranged between the vehicle seat 100 and the longitudinal adjustment mechanism 110 and / or the vehicle floor structure 109 (also referred to as the vehicle floor) and is used to connect the vehicle seat 100 (in particular the seat part 102) to the longitudinal adjustment mechanism 110 and / or the vehicle floor structure 109.

[0040] Figure 2 A perspective view of a vehicle seat 100, in particular a vehicle bench 100a, fastened to the longitudinal adjustment mechanism 110 is shown. The term vehicle seat 100 should be understood to refer in particular to a multi-component seat having a plurality of seating surfaces when viewed in the transverse direction y.

[0041] The longitudinal adjustment mechanism 110 shown in the figure includes four rail arrangements 112, in particular pairs of rails. The longitudinal adjustment mechanism 110 may also include only two rail arrangements 112 or three or more than four rail arrangements 112, which are arranged parallel to each other. The rail arrangements 112 extend along the longitudinal direction x of the vehicle seat 100.

[0042] Each rail arrangement 112 or each pair of rails includes a lower rail 116 and an upper rail 114, where the lower rail may be integrated, for example, into the vehicle floor, and the upper rail is mounted longitudinally movably within the lower rail 116.

[0043] The seat attachment structure 200 includes at least on one of the rail arrangements 112 a first attachment side 202 connectable to the vehicle seat 100 and a second attachment side 204 connectable to the longitudinal adjustment mechanism 110 and / or the vehicle floor structure not depicted in more detail. For example, the seat attachment structure 200 includes two lateral attachment carriers 206, each lateral attachment carrier having a first attachment side 202 and a second attachment side 204. In this case, each rail arrangement 112 may be associated with an attachment carrier 206.

[0044] In the case of the first bench 100a, at least the inner attachment carrier 206a or the internally located attachment carrier 206a may each be provided with at least one tolerance compensation device 210, also referred to as a tolerance adjustment device, Figure 3is shown in more detail to improve the connection or fastening of the vehicle seat 100 or bench 100a to the longitudinal adjustment mechanism 110 and / or the vehicle floor structure 109.

[0045] The seat attachment structure 200 can be designed as an adapter or an adapter module. In particular, the seat attachment structure 200 can be designed as a separate component or a separate pre-assemblable multi-part module. The seat attachment structure 200 serves on the one hand as an interface to the respective guide rail arrangement structure 112 and on the other hand as an interface to the vehicle seat 100, in particular to the respective seat part 102 (as Figure 1 shown).

[0046] The attachment carriers 206 for all the guide rail arrangement structures 112 of the vehicle seat 100 designed as a bench 100a can be rigidly connected to one another by means of the cross member 118.

[0047] Figure 3 A decomposition view of the seat attachment structure 200 according to the invention is schematically shown, which is used to connect the vehicle seat 100 to the longitudinal adjustment mechanism 110 and / or the vehicle floor structure not shown in more detail.

[0048] The attachment carrier 206 of the seat attachment structure 200 can have two carrier sides 208 arranged at intervals from one another in the transverse direction y. The carrier sides 208 are in the shape of plates. The carrier sides 208 are in particular designed as identical parts. Alternatively, the attachment carrier 206 can be of one-piece form, in particular a U-shaped carrier block, with two leg surfaces forming the carrier sides 208.

[0049] The attachment carrier 206 can be designed as an adapter or an adapter module. The attachment carrier 206 forms on the one hand a fastening interface with the seat part 102 and on the other hand a fastening interface with the guide rail arrangement structure 112 (as Figure 8 shown).

[0050] The attachment carrier 206 includes a first attachment side 202 connectable to the vehicle seat 100 and a second attachment side 204 connectable to the guide rail arrangement structure 112 and / or the vehicle floor structure not depicted in more detail.

[0051] The second attachment side 204 is equipped with at least one tolerance compensation device 210. For this purpose, the second attachment side 204 has at least one attachment opening 204.1 extending in the transverse direction y, in particular a through hole, in which the tolerance compensation device 210 is arranged, at least for compensating tolerances in at least one spatial direction, in particular for adjusting transverse tolerances.

[0052] In an improvement, the carrier sides 208 can each be characterized by an attachment opening 204.1, where the attachment openings 204.1 are arranged flush with each other in the transverse direction y.

[0053] A sleeve 204.2 (such as a metal sleeve) is arranged and fixed in the attachment opening 204.1. The sleeve 204.2 can be connected to the attachment opening 204.1 at least by form fit, force fit, and / or material bonding. When observed in the transverse direction y, the sleeve 204.2 can protrude beyond the respective attachment opening 204.1. Alternatively, the sleeve 204.2 can terminate flush with the attachment opening 204.1 (not shown).

[0054] The tolerance compensation device 210 includes at least one bearing bush 212 (such as a bearing sleeve) and two compensation elements 214, which can be arranged opposite to each other (or are arranged) within the bearing bush 212.

[0055] The bearing bush 212 can be a plastic sleeve. The bearing bush 212 can be inserted or is inserted into the sleeve 204.2. The bearing bush 212 can be connected to the sleeve 204.2 by form fit, force fit, and / or material bonding.

[0056] In an alternative configuration not shown in more detail, the bearing bush 212 can be omitted. In this embodiment not shown, the sleeve 204.2 directly forms the bearing arrangement structure for the compensation elements 214. In this embodiment, the compensation elements 214 are then directly arranged and held in the sleeve 204.2. In other words, in this embodiment not shown in more detail, only a single sleeve formed by the sleeve 204.2 is provided between the carrier sides 208, rather than the double sleeve formed by the sleeve 204.2 and the bearing bush 212 as depicted in Figure 3 and Figure 4 The description of the arrangement and bearing of the compensation elements 214 in the bearing bush 212 is similar to the description of the direct arrangement and bearing of the compensation elements 214 in the sleeve 204.2.

[0057] The compensation element 214 can be designed as a compensation adapter or a compensation adapter element. The compensation element 214 can be a hollow cylindrical adjusting element. The compensation element 214 can be designed as a sliding bush or a sliding sleeve.

[0058] Each compensating element 214 includes an internal thread 214.1. Each compensating element 214 includes a hollow cylindrical base body 214.2 and a flange section 214.3 arranged on the end face of the base body 214.2. The flange section 214.3 may have a larger diameter than the base body 214.2. The flange section 214.3 may form a contact section, in particular a flat contact surface, for supporting a fastening element 242 arranged against the guide rail arrangement 112 and / or a vehicle floor structure not described in more detail.

[0059] The crossbeam member 118 is positioned on the attachment carrier 206 between a first attachment side 202 and a second attachment side 204. In particular, the crossbeam member 118 is arranged and fixed in an offset section 206.1 at the end face of the attachment carrier 206. For example, the crossbeam member 118 is connected to the attachment carrier 206 in the region of the offset section 206.1 by form-fitting, force-fitting, and / or material bonding.

[0060] For example, the first attachment side 202 may be designed as a form-fitting, force-fitting, or material-bonding connection between the attachment carrier 206 and the seat part 102 (in particular a frame structure, a housing structure, or a similar structure). For example, the attachment carrier 206 may be connected to the seat part 102 in the region of the first attachment side 202 using screws, welding, or a similar method.

[0061] Figure 4 The seat attachment structure 200 in a pre-assembled state on the seat part 102 is shown, and the sleeve 204.2 is arranged in the attachment opening 204.1 of the attachment carrier 206, and the bearing bushing 212 is arranged in the sleeve 204.2, and the crossbeam member 118 is arranged on the attachment carrier 206.

[0062] Figure 5 It is shown that the compensating elements 214 are inserted or slid into the bearing bushings 212 along the transverse direction y, as indicated by the arrow 300. The compensating elements 214 are arranged relative to each other in such a way that the fixing elements 232 of the anti-rotation features 230 are properly interlocked.

[0063] Figure 6 The fully assembled tolerance compensation device 210 (initial state P1) is shown, in which the compensating elements 214 terminate flush with the end faces 212.1 of the bearing bushings 212 and / or the sleeve 204.2. Alternatively, the bearing bushings 212 and / or the sleeve 204.2 may each have a flange that abuts against the carrier side 208 from the outside.

[0064] In Figure 6 In the more detailed initial state P1 shown, each compensating element 214 terminates flush with the corresponding end face 212.1 of the bearing bushing 212 and / or the corresponding end face of the sleeve 204.2.

[0065] In particular, each of the compensation elements 214 is inserted or pushed far enough into the bearing bush 212 such that the inner surface of the respective flange section 214.3 contacts the respective end face 212.1 of the bearing bush 212. Using Figures 9 to 11 at least one connecting element 220 (such as a screw element) more particularly depicted in Figure 9 FIG., the compensation element 214 can be moved from an initial state P1 (as Figure 11 shown) to a compensation state P2 (as

[0066] shown), particularly for tolerance compensation or tolerance adjustment. Figure 5 To prevent the compensation element 214 from rotating during the screwing in of the connecting element 220, the compensation element 214 can each have an anti-rotation mechanism 230 at its finished surface end (as

[0067] shown). The anti-rotation mechanism 230 provides an "anti-rotation function". The anti-rotation mechanism 230 is arranged to prevent the compensation elements 214 from rotating relative to each other when the connecting element 220 (particularly a screw) is tightened. For example, the connecting element 220 is used on both sides of the tolerance compensation device 210, engaging with the respective compensation elements 214, particularly in a threaded engagement. Figure 5 shown).

[0068] In the initial state P1 (as Figure 6 shown), when both compensation elements 214 are fully arranged within the bearing bush 212, the fixing elements 232 can be interlocked such that the compensation elements 214 support each other against rotation and prevent rotation.

[0069] Figures 4 to 6 The assembly process of assembling the tolerance compensation device 210 into the seat attachment structure 200 is schematically shown in a perspective view.

[0070] Figure 4 The bearing bush 212 pre-assembled in the sleeve 204.2 of the attachment carrier 206 is shown. The bearing bush 212 can be pressed into the sleeve 204.2. The bearing bush 212 is arranged and held in the sleeve 204.2 by form-fit and / or force-fit.

[0071] Figure 5It is shown that the compensation element 214 is inserted or slid into the bearing bush 212 on both sides along the transverse direction y, as indicated by the arrow 300. The compensation elements 214 are aligned with each other such that the fixing elements 232 of the anti-rotation mechanism 230 are properly interlocked. The bearing bush 212 is arranged on the attachment carrier 206, passing through the two carrier sides 208. The end face of the sleeve 204 and the end face 212.1 of the bearing bush 212 are flush with each other.

[0072] Figure 6 The fully assembled tolerance compensation device 210 (initial state P1) is shown, in which the compensation element 214, in particular its angled collar portion or outer flange section 214.3, rests on the end face 212.1 of the bearing bush 212 (as Figure 5 shown) and / or on the end portion located on the end face of the sleeve 204.2.

[0073] Figure 7 A side view of the vehicle seat 100 is schematically shown, and the vehicle seat is arranged on the longitudinal adjustment mechanism 110 with the seat attachment structure 200. As previously described with the aid of Figure 5 and Figure 6 the seat attachment structure 200 includes two carrier sides 208 of the attachment carrier 206 as the first attachment side 202 ( Figure 7 only one of the carrier sides 208 is shown).

[0074] As the second attachment side 204, the seat attachment structure 200 includes at least one fastening structure 240 with at least one fastening element 242.

[0075] The at least one fastening structure 240 is used to fasten the seat attachment structure 200 to the longitudinal adjustment mechanism 110. For example, the fastening structure 240 can be connected to the guide rail arrangement structure 112, in particular to the upper guide rail 114. Alternatively, the fastening structure 240 can be arranged to fasten the vehicle seat 100 to the vehicle floor not shown in more detail and create a suitable vehicle floor structure.

[0076] A tolerance compensation device 210 is provided to compensate for the tolerance between the attachment carrier 206 of the vehicle seat 100 and the fastening structure 240 of the longitudinal adjustment mechanism 110.

[0077] The tolerance compensation device 210 is particularly arranged in the region of the second attachment side 204 of the seat attachment structure 200 (as Figure 8 shown in detail).

[0078] For tolerance compensation, two tolerance compensation devices 210 can be provided, in particular a first tolerance compensation device 210.1 in the front region of the seat attachment structure 200 and a second tolerance compensation device 210.2 in the rear region of the seat attachment structure 200.

[0079] The attachment carrier 206 (in particular its attachment opening 204.1), the fastening structure 240 (in particular its fastening opening 244), and the tolerance compensation device 210 (in particular the through-hole 214.4) are arranged and positioned in such a way that on both sides of the seat attachment structure 200 (as Figures 8 to 11 shown), the connecting element 220 can be inserted into the tolerance compensation device 210 (in particular the associated compensation element 214) to connect the attachment carrier 206 and the fastening structure 240. In this case, by means of the tolerance compensation device 210 arranged between the attachment carrier 206 and the fastening structure 240, the tolerance in at least one spatial direction can be adjusted, in particular the tolerance in the longitudinal direction x, the vertical direction z, the transverse direction y, and / or the radial direction r.

[0080] The through-hole 214.4 of each compensation element 214 is in particular smaller than the attachment opening 204.1 and smaller than the fastening opening 244. The attachment opening 204.1 is larger than the through-hole 214.4 and smaller than the fastening opening 244.

[0081] Figure 8 The seat attachment structure 200 is shown, in which the attachment carrier 206 is arranged between two fastening elements 242 of the fastening structure 240. The attachment carrier 206 in turn has two carrier sides 208 (also referred to as carrier plates or carrier surfaces) which carry attachment openings 204.1 for receiving the tolerance compensation device 210.

[0082] The fastening structure 240 can have at least two fastening elements 242 arranged spaced apart from each other in the transverse direction y, for example two separate fastening plates arranged parallel to each other or two fastening arms 242.1, 242.2 of a one-piece U-shaped fastening element 242. The seat attachment structure 200, in particular the attachment carrier 206, is arranged in the intermediate space 242.3 formed between the two fastening arms 242.1, 242.2, in particular in a receiving space or a hollow space.

[0083] The fastening elements 242, in particular two fastening arms 242.1, 242.2, can each have two fastening openings 244 that are aligned with each other in the transverse direction y for inserting connection elements 220, in particular screw elements. Each fastening opening 244 can be "oversized". The dimensions of the fastening openings 244 in the radial direction r, the vertical direction z, and / or the longitudinal direction x can be larger than the hollow spaces, in particular the through-holes 214.4, of the respective compensating elements 214, so as to allow tolerance adjustment or tolerance compensation in the radial direction r, the y-direction, the x-direction, and / or the z-direction. Such "oversized" fastening openings 244 allow the seat attachment structure 200, in particular the attachment carrier 206 and the fastening structure 240, to be positioned relative to each other without tension and in alignment, and, by means of the tolerance adjustment device 210, to compensate for the positioning of the attachment carrier 206 and the fastening structure 240 relative to each other in the radial direction r, the y-direction, the x-direction, and / or the z-direction. In this way, the clicking noise during adjustment of the vehicle seat 100 can be greatly reduced or even eliminated.

[0084] Figures 8 to 11 Schematically depicts the fastening process of connecting the vehicle seat 100 to the longitudinal adjustment mechanism 110.

[0085] Figure 8 Shows the seat attachment structure 200 arranged between the fastening elements 242 of the fastening structure 240, where the tolerance compensation device 210 is aligned with the fastening openings 244 of the respective fastening elements 242. In this case, there may be a gap or play between the fastening structure 240 and the seat attachment structure 200 in the radial direction r, the x-direction, the y-direction, and / or the z-direction. The seat attachment structure 200 and the fastening structure 240 do not need to be under tension, for example preloaded, relative to each other. For this purpose, a corresponding tolerance compensation device 210 is provided.

[0086] For example, the fastening structure 240 can be fastened to a first guide element 114, for example to the upper guide rail.

[0087] In particular, the fastening structure 240 can be connected to the upper guide rail 114 by means of a fastening portion 240.1 (such as a rivet connection, a screw connection, a welding connection, or a similar connection).

[0088] To enhance strength and stiffness, the fastening structure 240 may include additional fastening elements 243, in particular another U-shaped fastening element 243 with fastening arms 243.1, 243.2. The two fastening elements 242, 243 are designed to correspond to each other such that, for example, they can be inserted into each other and connected in a form-fitting and / or force-fitting manner, in particular by frictional engagement, and additionally, they are also connected to each other via the fastening portion 240.1 and connected to the upper guide rail 114. The fastening element 242 (also referred to as the inner fastening element 242) provides an inner contact surface for the compensating element 214. The other fastening element 243 (also referred to as the outer fastening element 243) provides an outer contact surface for the connecting element 220. The two fastening elements 242, 243 can be separate or integrally formed.

[0089] Figure 9 It is shown that the connecting elements 220 are placed on both sides of the fastening structure 240, where each compensating element 214 has an associated connecting element 220. The respective connecting elements 220 can be locking screws.

[0090] Figure 10 It is shown the initial tightening of the respective connecting elements 220. As indicated by the arrow 302, by rotating the connecting element 220, each compensating element 214 is displaced out of the bearing bush 212 along the transverse direction y until the flange section 214.3 contacts the inner contact surface (in particular with the inner fastening element 242), and thus is supported along the transverse direction y.

[0091] The geometry of the anti-rotation mechanism 230 prevents rotation during tightening and the application of torque via the connecting element 220. The compensating elements 214, in particular the fixing elements 232, contact and support each other to prevent rotation. When this occurs, the compensating element 214 continues to move outwards along the transverse direction y, in particular until the final position, in particular the compensation state P2, has been reached.

[0092] Figure 11 It is shown the tolerance compensation device 210 in the compensation state P2, where the compensating element 214 is arranged in the bearing bush 212 and its flange section 214.3 rests against the inner fastening element 242 to compensate for the lateral tolerance in the transverse direction y. The seat attachment structure 200 is now connected to the fastening structure 240 in a torsion-free or low-torsion manner, where the tolerances that can be generated by the structural elements can be eliminated.

[0093] Figures 12 to 15Another fastening process for fastening a vehicle seat 100 to a longitudinal adjustment mechanism 110 is schematically shown in a front view, in particular via a seat attachment structure 200, by means of these two tolerance compensation devices 210.1 and 210.2 together with the components to be connected (attachment carrier 206 and fastening structure 240), in an initial state P1, using two tolerance compensation devices 210.1, 210.2, which are designed and constructed in the same way as the aforementioned ones.

[0094] Figures 12 to 15 The fastening process shown follows the same method as Figures 8 to 11 the fastening process described, and the seat attachment structure 200 may have a plurality of tolerance compensation devices 210, which can be tightened simultaneously or at the same time using connecting elements 220.
